The invention is a rail chair. The object of the invention is to providea rail chair which is a combination tie plate and rail brace of unitaryconstruction which 1 will positively position itself in a tie and babsorb the lateral thrust of the rails, especially on curves.

Another object of the invention is to provide a rail chair as outlinedwhich will be light in weight positively retained in position on a tie,readily reinoved'and replaced, by and which will permit a certainflexibilityin the rail, and being so formed adjacent the spike holes asto permit convenient nianipula tion oi 'a spike puller for withdrawingthe:

spikes.

The invention consists primarily of a tie plate having an integral railbrace extend ing throughout its length and fitting close 1 2 iv to theflange and flange fillet and having a slight clearance at the up oerortion of the web and web-ball fillet and tne ball, the brace clearingthe greater portion oi the web, and

provided with a core extending longitudinal iy therethrough, the outerwall being inclined v at angle of substantially forty five degrees,

and the tie plate having integral ribs on the bottom tace diagonally andlongitudinally disposed, the inner side or" the tie plate upper surfacecontinuing as a flat base to a point approximating the outer edge of thespike holes thence extending upwardly to coincidence with a planetangential to the inclined upper surface of the rail flange, andCOIltlllllr 3:; ing outwardly at similar inclination to the edge of theplate, spike holes being placed out of transverse alignment.

Referring to the accompanying drawings: Fig. l is atop plan view of theinvention;

Fig. 2 is a bottom plan view showing the embedding ribs; 1 Fig. 3 is atransverse section taken on line 3-3 of Fig. 2 and indicating a rail andspikes in position. I

Similar reference characters. are used to.

designate similar parts throughout the several views. t The tie plate 4is providedon its undersur lane with diagonal embedding ribs 5 and 101i-.50 gitudinal ribs 6 which are adaptedto embed at 20, "forthe purposeofreducing weightand in the 'tiedue to weightbfthe rolling stock,thereby keying the plate to "thetie. -A

plurality of spike holes 7 -andfS' areout'of transverse alignment toprevent splittingpf the ties by thespikes. f i The upper surfaceof theplate is pro vided with a flat flange receiving portion 9 extendingoutwardly to adjacent the outer edge of the spike holes 8, thence havinga vertical shoulder 10 terminating at 'coi'nciruto dence with anextensionofthe inclined sur' face 11 of a rail flange, thenextendingtothe edge of the plate'ivith the sameinclination as at 12 thusproviding a, shoulder for the back surface or the spike l3 adj acenttle' head.

The rail. brace 14 is castior formed integral with the'tie plateandforms an angular re 1 cess. with thetie, plate asja't 15, forcooperation with theflangeof the rail and continuing into a shoulder "16cooperating 'jwith the 7 ."lOWBl pOrtio'n of the rail webthencecont'inii I ing with a portion 17: clearing the Web, the upper portion18 slightly clearing the upper p'ortionot the weband lower face of itheball of the rail, the fouter wall l9,b'eing inclined at an angle'oiiappronin ately forty five "de greesterminatingin. ith-e tie plate.The brace 1a is cored'throughout its length, as

econoinizing on material. I

V I so Installation otthe device is'accomplishd I by passing the tieplate. under the rail and ontop of the tie, and driving'theffspilres 13which by cooperation with the shoulder 10 lock the rail in position.slight transve'rse; flexure ofthe Tall. is necessary to formecontactfatthe shoulder 18before' the brace 14 is i brought into"action; and the, emb dcling of. the ribs 5 and 6 inthe' tieeffectivelyretain the plates and coincidently. the rail in the-i irelative positions; H "1 lam awarethat'rai-l chairs, tie-platesand railbraces have-been n1ade,- therefore I do not clai n such devices'broa'd-lybut ill:

claimi f I 1. A rail chair coinprisingaftie-plate and rail brace of untary construction; said'rail' brace being adapted to engage the lowerpor tionof the webof a" rail andto islig htly cleaif 10:0 7

the upper portion of the web and underof the plate in a prolongation ofthe inclined surface of the ball of a rail.

2. A rail chair comprising a tie plate and rail brace of unitaryconstruction, said rail brace being formed so as to engage the uppersurface of a rail flange and the lower portion of the rail web, theupper portion of said brace slightly clearing the upper portion of therail web and undersurface of the rail ball, said rail brace extendingthroughout the length of said tie plate.

3. A rail chair comprising a tie plate and rail brace of unitaryconstruction, said rail brace being formed so as to engage a rail flangeand the lower portion of the rail web, the upper portion of said braceslightly clearing the upper portion of the rail web and the undersurface of the ball ofthe rail, said rail brace extending diagonallydownward from the ball portion to the tie plate.

4. A rail chair comprising a tie plate and a rail brace of unitaryconstruction and of equal length and formed so as to engage the flangeof a rail and the lower portion of the Web thereof, and a ball engagingportion normally slightly clearing the'upper portion of the web andunder surface of the ball of a rail, continuing therefrom diagonallyclown- Ward to said tie plate, the body of said brace having asubstantially triangular aperture formed longitudinally therethrough.

5. A rail chair comprising a tie plate and 'a rail brace of unitaryconstruction and of equal length and formed so as to engage the flangeand lower web portion of a rail, the upper section of said brace beingnormally out of contact with the upper portion of the web andundersurface of the ball of said rail, continuing therefrom diagonallydownward at an angle of approximately forty-five de grees to said tieplate, the body portion of said brace having a triangular lighteninghole cored therethrough longitudinally said tie plate having a pluralityof projecting ribs on the undersurface adapted to embed in a tie.

diagonal and longitudinal embedding beads on the undersurface of saidtie plate, a pluralltyof spike receiving apertures 1n longitudinal butnot transverse alignment, a

shoulder extending throughout the length of said tie plate coincidingwith the outer edge of the spike receiving apertures, and in acontinuation of the plane of the upper surface of the rail flange,continuing to'the edge surface of said rail flange.

In testimony whereof I have affixed my signature.
